Venturi Working Theory
time:2013/8/30
Venturi injector is one of device of gas- liquid mixture, which adopt PVDF material that has the feature of oxidation
resistance or corrosion resistant; Currently venturi injector widely used for ozone water mixing, sewage treatment,
medicine field due to the feature of ozone resistance, long service life, good mixing effect!
1. Body material: PVDF; PVDF is a natural, high purity material without pigment;PVDF materials with chemical
corrosion resistance and solvent resistance properties are excellent; as the fluorine plastics, the heat resistance of
PVDF are higher than all the other plastics, heat resistance up to 148 ℃; PVDF is a hard material, highly crystalline,
abrasion resistance excellent, high mechanical strength, impact resistance, long service life.
2. The main models (waterway diameter named): 1/5 inch , 1/2 inch, 3/4 inch , 1 inch, 1.5 inch, 2 inch;
Application:
Widely used in water treatment (dissolved ozone and chlorine dioxide sterilization, oxygenation in addition
to iron), chemical industry, aquaculture, direct drinking water machine, petroleum, machinery, electric power,
metallurgy, textile, ships, instruments and national defense industry etc.
The advantages:
1. simple structure, safe operation, low cost, quick effect, no power consumption;
2. Not affected by all kinds of radiation, electromagnetic waves, and has corrosion resistance, earthquake, explosion
and high and low temperature resistance and other characteristics, suitable for application in a variety of environments;
3. Jet element can be made very small, and the electronic technology can be integrated.
Disadvantages:
The action is slow compared with the electronic components, and can’t remote control.
Working principle:
In the high-speed rotating impeller, the liquid from the nozzle at high speed, high-speed flow of liquid through the
gas mixing chamber, will form a vacuum in the gas mixing chamber, the airway inhalation of air, air into the gas
mixing chamber, lodged in the throat and intense mixing liquid, to form gas-liquid mix by diffusion tube, exhaust,
air rises with fine bubbles in the water, efficient mass transfer form in the whole process. Can used for the
disinfection of sewage, purification
